ANESTHETIG-DISPENSER.

Application filed October 15, 1913.

a To all whom it may concern:

Be it known that I, SACKS Bnrcnnn, a citi zen of the United States of America, and a resident of Vvashington, in the District of Columbia, have invented certain new and useful Improvements in Anesthetic-Dispensers, of which the following is a description, reference being had tofthe accompanying drawings, forming a part of this specification.

My invention relates to that class of dispensers which are used to dispense ether or other anesthetic during the progress of surgical operations and my improvement con sists in providing a dispenser with a novel construction of dispensing tube having a novel construction of indicator and which will enable a definite quantity of anesthetic to be dispensed automatically and with regularity at a predetermined rate without th constant attention of a trained anesthetist.

In the drawings, Figure 1 is an assembly view of my improved apparatus applied to a conventional table; Fig. 2 is an elevation of the dispenser from an opposite side; and Fig. 3 is a vertical section of the same, parts being in elevation.

For commercial purposes the apparatus embraces three parts, a securing bracket or clamp A, a flexible supporting arm B, and a container 0 having a readily accessible filling device, and a dispensing tube having an adjustable indicator valve. In each instance I have devised a special construction with especial reference to theparticular use to which the apparatus is to be applied, although the particular construction of the dispenser is the main feature of the invention.

The bracket or clamp A comprises a U- shaped piece 11, carrying a socket 12, having a thumb screw 13, a clamping screw-rod 141, having a thumb piece 15, and a large pivoted head 16 faced with suitable material 17 for preventing injury to the table to which the clamp is applied. y

The flexible supporting arm B comprises a stiff portion 18, passing through the socket 12 and having its upper end provided with an interior screw thread to receive a corresponding outer screw thread on the lower end of a flexible portion 21 slightly stiffened by an interior longitudinal wire and carrying at its farther end a snap hook 23, preferably turning with some friction.

Specification of Letters Patent. v Patented Sept, 15, 1914,

Serial No. 795,218.

The dispenser comprises a body 25 having 1 heads 26 and 27, the upper head 26 having an air vent or inlet 28 controlled by a cap 29 and further having attached thereto chains 30, preferably three in number in order to prevent unintended rotation or oscillation the chains being attached to a ring 2 1 which en'- gages the snap hook 28. The lower head has attached thereto a depending dispensing tube 31, through which the anesthetic gravitates in minute drops, having an upper inclined longitudinal hair-like bore 32 communicating with the interior of the body 25, a lower inclined longitudinal hair-like bore 33 communicating with the outer air and a horizontally disposed hair-like bore 34 connecting the bores 32 and 33 and controlled by a hair-like needle valve 35 operated by a thumb screw 36 on its enlarged screw threaded portion 37 which also carries a circular indicator disk 38 with suitable marklugs 39 on its periphery registering with the edge of a peripheral segmental slot 1O in the periphery of a half-casing rim 41 formed as a boss on one side of the depending dispensing tube 31. The valve 35 of the olepending dispensing tube 31 can therefore be operated with the fingers of one hand and the markings read on the periphery of the indicator disk from one side of the table.

The body 25 is provided with a vertically disposed gage 42 communicating through ing orific 4-5 to receive the anesthetic, said orifice communicating with the interior of the body 25 through the channel 46 and being closed by a cap 47 held shut by a spring 48.

Practical use of an apparatus construct ed in accord with my invention as herein set forth proves that it allows of definite calculations being made as to the amount of anesthetic necessary to complete an operation,saves about 30 per cent. of the anesthetic in th case of ether owing to the definite regulating feature, permits the anesthetist to continually watch the patient and a less skilled anesthetist to administer, and conduces to th cleanliness and simplicity of the anesthetizing operation, only a mask being necessary in addition to the dispenser Finally it removes the constant source of danger of the killing or injuring of the patient such as a result from the spilling of the -Having thus described my invention the following is What I claim as new therein and desire to secure by Letters 1 Patent.

An anesthetic dispenser comprising a body having a'chamber for containing the anesthetic, and a dependingdispensing tube through which the anesthetic gravitates in minute dr0ps,vhaving'an upper logitudinal Copies of this patent may be obtained for five cents each, by addressing the Commissioneifot Patents;

llHlfOIDlQCllS a boss on one side of the dis pensing tube, provided with a peripheral segmental slot at the front side ofthe rim and a thumb-screw having an enlarged screw-threadedp0rt1on working in the dispensing tube and a hair-like needle valve controlling the transverse connecting bore,

and a" circularindicator disk having markings on its periphery and located within the half-casing rim.
